Youngstown police are still trying to figure out who's responsible for a nightclub shooting that left one dead and two others hurt. 

Officers responded to the shooting at Utopia nightclub on the 800 block of East Midlothian Boulevard around 1:30 a.m. Officials heard several more gunshots at the bar as they arrived on scene, according to a release from the Youngstown Police Department. 

"When officers responded, there were still a couple shots fired when they walked through the door. We think the shots might have been possibly fired in the back of the crowd. None of the officers were struck by gunfire or exchanged rounds with anybody," said YPD Captain Rod Foley.

Officers on scene requested back up and officers from Austintown, Struthers and Boardman responded to help with crowd control.

The officers inside the bar attempted to find the shooter but were not able to locate the suspect.

While searching the bar, police found three shooting victims and had them taken to St. Elizabeth Hospital.

A 27-year-old man was pronounced dead at the hospital.

A 21-year-old man and a 20-year-old woman are being treated for gunshot wounds.

Councilwoman Basia Adamczak would like to know whether the occupancy guidelines were followed and necessary safety precautions were taken.

"I don't know if they had security at the door. I don't know if they are checking for weapons. I'm not aware if that was occurring, but I believe that is necessary anytime there is such an event," said Adamczak.

The event was promoted as having security, but what quality and how many were working is a question city officials want to know.

Police are not allowed to work security at bars or events like this without an insurance policy. 

Councilwoman Anita Davis says officers were not working the scene but were close by.

The city was aware of the event that was being promoted, but they had no idea hundreds of people were attending.

We reached out to the owner of Utopia to ask those questions but have not heard back from him. 

Youngstown Mayor Jamael Tito-Brown emphasized police are doing everything possible to catch the suspect or suspects.

"I think it's a matter of time before we find these individuals. We're talking about a small minute group of individuals who are committing these crimes," said Mayor Tito-Brown. 

Youngstown Police and the Mahoning County Coroner's Office are investigating the shooting.

Anyone with information on the shooting can call 330-746-CLUE or 330-742-8YPD to leave a tip.

Those with information that leads to the arrest and conviction of the suspect will be eligible for a cash reward.
